high-gain power amplifier
21Buffer amplifier — A buffer amplifier (sometimes simply called a buffer) is one that provides electrical impedance transformation from one circuit to another. Two main types of buffer exist: the voltage buffer and the current buffer. Figure 1: Top: Ideal voltage… …
22Magnetic amplifier — The magnetic amplifier (colloquially known as a mag amp ) is an electromagnetic device for amplifying electrical signals. The magnetic amplifier was invented early in the 20th century, and was used as an alternative to vacuum tube amplifiers… …
23Audio amplifier — An audio amplifier is an electronic amplifier that amplifies low power audio signals (signals composed primarily of frequencies between 20 hertz to 20,000 hertz, the human range of hearing) to a level suitable for driving loudspeakers and is the… …
24Valve audio amplifier — A valve (UK) audio amplifier or vacuum tube (US) audio amplifier is a valve amplifier used for sound recording, reinforcement, or reproduction. Until the invention of solid state devices such as the transistor, all electronic amplification was… …
25Instrument amplifier — This page is about amplifiers for musical instruments. See also instrumentation amplifier, a type of operational amplifier. An instrument amplifier is an electronic amplifier that converts the often barely audible or purely electronic signal from …
26Optical parametric amplifier — An optical parametric amplifier, abbreviated OPA, is a laser light source that emits light of variable wavelengths by an optical parametric amplification process. Contents 1 Optical parametric generation (OPG) 2 Optical parametric amplification… …
27Crossed-field amplifier — A crossed field amplifier (CFA) is a specialized vacuum tube, first introduced in the mid 1950s and frequently used as a microwave amplifier in very high power transmitters. Raytheon engineer William C. Brown s work to adapt magnetron principles… …
28Distributed amplifier — Distributed amplifiers are circuit designs that incorporate transmission line theory into traditional amplifier design to obtain a larger gain bandwidth product than is realizable by conventional circuits. N stage traveling wave amplifier …
29Peavey 5150 Amplifier — The Peavey 5150 Amplifier was an all tube guitar amplifier made by Peavey Electronics from 1991 present, that was made as a signature model for Edward Van Halen. The amp series was designed by a partnership of Peavey Engineers and Edward Van… …
30Operational transconductance amplifier — Schematic symbol for the OTA. Like the standard operational amplifier, it has both inverting (−) and noninverting (+) inputs; power supply lines (V+ and V−); and a single output. Unlike the traditional op amp, it has two additional biasing inputs …
